Hi ML,
For 200 CDs to be stored on the Brennan, volume sizes will be approximately as follows.
110 GB for WAV format (uncompressed)
52 GB for FLAC format
20 GB for mp3 256K format
10 GB for mp3 128K format.
The most popular format to rip to is FLAC format. This is because FLAC is lossless and you can reconstruct a CD back from the FLAC file and have no data loss. If you compress to any MP3 format, some of the music data will be lost in the compression process and can not ever be recovered.
Regards,
Peter.
